I decided to get a new chuck key for my DP and, not knowing any better, went
to the Enco site. Well, I didn't buy my DP or its chuck from Enco so I
can't match any of their letter-sizes to what I have.

What is the normal method for specifying a chuck key size? Isn't it the
diameter of the pilot hole?

TIA

Chick designers have a huge database of all chuck keys ever made. When they
have to design a new chuck they make sure that none of the existing keys will
fit.
Last chuck key I bought was from milwaukee. The card it came on had a
cross reference chart on the back.
